25 designates the piston which is here shown as movable in a passage 26 formed in the generator in line with the outlet 15 and separated therefrom, the piston having a pin 27 projecting therefrom which terminates i a needle valve 28 movable into and out of the outlet 15 which is a small jet opening. The

piston passage 26 as shown in Fig. 2 is connected to the inlet and outlet end of. the passages 11, 12.

'l he pressure on the piston opposed to the pressure of the gas in the generator may be provided with a spring, Fig. 6, a weight, F 7 or by the pressure within the tank 19, either directly through the oil or by a pipe 29 leading from the upper part of the tank to the rear end of the piston 25.

Preferably, as here shown, in Fig. 2, this pressure is provided by the pressure in the tank through the oil being fed from the tank by such pressure and the rear face of the pieton 25 is exposed to the inlet for the oil,and a check valve 30 is provided within the passage 11 of the generator for preventing the pressure of the gas in the generator from acting upon the rear face of the piston; and in the embodiment illustrated in Fig. 2, the pisston also cuts off the inlet for the oil to the passage .11 when operated to open the outlet 15 by the pressure of the gas in the generator.

However, if desired, the check valve be omitted and the back pressure of the gas stop the flow of the oil when such back pressure becomes greater than the pressure within the tank, in which case, the piston 25 may be opened against the spring 30", Fig. 6, or against the pressure within the piston chamber 31 connected by the pipe 29 to the top of the tank with the piston chamber, Fig. 5.

in the construction shown in Figs. 5, 6 and 7, the piston chamber does not open into the inlet end of the generator but said chamber is separated therefrom by a wall and such chamber opens only into the outlet or gas pressure part of the generator.

In Fig. 7, the piston 83 is moved in the piston chamber 3% and is connected to a weighted lever 35 acting in opposition to the gas pressure, the lever carrying a needle valve 36 which opens and closes and cleans out the outlet 37.

As shown in Fig. 2, the pipe 21 from the tank 19 is not connected directly to the inlet for the generator but to a receiver 88 having a pressure chamber 39 separated from the outlet 39 of the receiver by a partition depending from the top of the receiver and terminating near the bottom thereof. The air trapped in the chamber 39 is compressed by the fuel oil passing into the receiver and the pressure of oil from the tank 19 and tends to open the piston 25 more quickly, that is, make the operation more sensitive than when a pressure chamber is not used. The pres sure within the tank 19 is maintained by a pump not shown, as a hand pump in small installations and an automatically controlled power pump in larger installations.

In operation, the generator 9 is first heated as by alcohol poured on the top face of the burner and ignited, and when suiiiciently hot vaporizes the oil passing therethrough, and the pressure of the gas generated operates the piston 25 to open the outlet 15, whereupon the gas passes through the conduit or mixing chamber 16 w iere it mixes vith air entering at 17 and then into the hollow burner, and out through the jet openings or slots i, 5, where it is ignited and continues to heat the generator as well as a boiler or hot air pipes, or other things to be heated.

When the gas is free to pass out of the out let 15 either the piston 25 closes the inlet for the oil to the generator, or the pressure within the generator is sufiicient, to hold the oil from flowing into the generator. l-lence, after the oil in the generator has been vaporizeol the pressure in the generator falls and the pressure in the tank containing the oil either through the oil or directly, moves the piston 25 to close and clean out the outlet 15.

When the piston 25 is in this position, the oil feeds into the generator and the generator again generates gas until the pressure of the gas again moves the piston 25 to open the outlet 15, and this operation automatically repeats the piston fluctuating back and forth, automatically controlling the gas genera ted and cleaning out the opening 15.
